THERAPEUTIC LAMP.

Application filed Hovember27, 1928. Serial No. 151,158.

The main object of this invention is to provide an improved therapeutic lamp for use in bath cabinets and the like which is highly efiicient in the production of intra red rays. f

A further object is to provide a lamp or therapeutic unit of the class described which may be used without liability of injury to the patient or the operator.

()bjects pertaining to details and economies of my invention will definitely appear from the detailed description totollow. The invention is clearly defined and pointed out in the claims.

A. structure embodying the features of my inventionis clearly illustrated in the accompanying drawing forming a part of this application, in which:

Fig. 1 is a fragmentary side elevation of a lamp or unit embodying the features of my invention.

Fig. 2 is a section on a of Fig. 3.

Fig. corresponding to line 33 .of Fig. 2.

Referring to the drawing, my improved therapeutic lamp unit comprises a base 1 having a central opening 2 therein shouldered at 3 to form a seat'for the socket plug a which, in the embodiment illustrated, is adapted to fit or coact with the common form of lamp socket.

The resistance Wire 5 is mounted upon the core 6 which has a spiral groove to receive the Wire, thereby keeping the coils thereof properly separated. This core is preferably formed of lava. Around this core is a lava tube 7 which is of such dimensions that it is spaced from but its inner side lies adjacent to the resistance wire and core so that the tube is heated from the resistance element. The lower end of the tube is seated in the opening 2 in the base upon the plug a.

A yoke-like frame 8 is mounted on the fragmentary view partially in line corresponding to line 2-2 base and carrles a screw 9 which clamps the cap 10 upon the end of the tube, this cap being recessed to receive the end of the tube.

The parts are thus maintained in fixed re lation when assembled and at the same time permit easy assembling and disassembling This cap 10 is also preferably of lava.

The cylindrically curved segmental reflector 11 is of black iron which reflects only 3 is a horizontal section on a line My improved lamp or therapeutic device is especially designed by me for use in bath cabinets and treatments where intra red rays are desired and l have. illustrated and described my improvements as l have embodied the same for that purp se. it have not attempted to illustrate or describe certam modifications Or adaptations which I 'contemplate as I believe this disclosure will enable the adaptations or embodiment I of the invention as may be desired.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. in a device of the class described, the combination of a base having a central shouldered opening therein, a yoke-like frame carried by said base, a socket plug,

seated on the shoulder in said opening of said base, a core on sziid plug having a resistance coil thereon, a tube disposed over said core with its lower end within said base opening and seated on said socket plug, a cap of lava recessed to receive the upper edge of said tube, a screw threaded into said frame to engage said cap, a cylindrically curved segmental reflector mounted to embrace the edge of said base, and a segmental curved foraminated guard mounted xtO embrace the opposite side of said base, the edges of said reflector and guard being overlapped within and clamped to said base by said frame, said frame constituting a support for said reflector and guard.

2. In a device of the class described, the combination of a base having a central shouldered opening therein, a yoke-like frame carried by said base,a socket plug seated on the shoulder in said opening of said base, a core on said plug having a resistance coil thereon, a'tube disposed over said core with its lower end within said base opening and seated on said socket plug, a

frame to engage said cap.

cap oflava recessed receive the upper edge of said tube, and a screw threaded into said 3. In a therapeutic device, the combination of a base having an opening therein, a

a core of lava carrying a resistance element,

a tubular radiating element embracing said core, a cylindrically curved segmental reflector of black metal mounted on'said base, and a segmental curved foraminated guard mounted on the opposite side of said base,

' the edges of said reflector and guard being overlapped within and clamped to said base by said frame, said frame constituting a support for said reflector and guard.

5 In a therapeutic device, the combina- Vtion of a base, a core of lava carrying a resistance element, a tubular radiating element embracing said core, a cylindrically curved segmental reflector of black metal mounted reeeaso on said base, and a segmental curved foraminat-ed guard'mounted' on the opposite side of said base.

6. In a therapeutic device the combination of a base, a heating element comprising a core of lava having a resistance thereon, a tubular radiating element embracing said core and disposed in close proximity to but spaced from the said heating element, a yoke-like frame on' said base member, a cap recessed to receive the upper end of said radiating element, and a screw threaded through said frame to engage said cap.

7. In a structure of the 'class described, the combination of a base, a heating element mounted thereon and comprising a core having a resistance clement thereon, a tube'of earthy material embracing, said core to be heated by said resistance element, and a cylindrically curved reflector of black metal.

8. A structure of the class described comprising a socket plug, a heating element thereon comprising a core, a coil of resistance Wire on said core, and a tube of lava embracing said core with its Wall in close proximity to but spaced from said core whereby the tube is heated from said heating element.

In witness whereof I have hereunto set any hand. i
